百度地图的api句柄
baidumap的Python项目详细描述
百度地图API
说明
本模块是百度地图的python开发包。你只需要写一些代码就可以得到一个可执行的效果。此外，经过一些修改后，此模块还可以在另一个MAP API上工作

开始
pip install baidumap
使用pip安装，只需要请求。

手柄
工厂模式
从工厂函数获取句柄get_handle
frombaidumap.api.handleimportget_handle
使用baidu map web api中的名称
示例
检查
http://api.map.baidu.com/place/v2/search?query=ATM机&tag=银行®ion=北京&output=json&ak=您的ak///获取{p>
api路径是http://api.map.baidu.com/place/v2/search（最后的/是否非常重要）
所以这个句柄的名称是place/v2/search（只需删除api路径的头即可）
# ak_key is the authority key of the baidu map# you need to apply for it from ('http://lbsyun.baidu.com/index.php?title=%E9%A6%96%E9%A1%B5')ak_key='********************'# you can set params when get it from factory# (the first two is not params, they are ak_key and handle's name)# set is_list: true to get multi-page resultplace_search=get_handle(ak_key,'place/v2/search',is_list=True)# then use method set_params() to set request parameterplace_search.set_params(query='ATM机',region='北京')# use method run to get result# you can limit the max_page_num(=-1 not limited), page_size(=10, limited by baidu mao), max_result_num(=-1 not limited) and interval(=0 second between each request(too frequently request will be block by baidu map and baidumap.api will raise baidumap.api.exceptions.BaiduMapApiException))# place_search.run([max_page_num=-1[, max_result_num=-1[, page_size=10[, interval=0]]]])atm_in_beijing=place_search.run(max_page_num=3,page_size=20,max_result_num=55,interval=0.5)# get resultprint(atm_in_beijing)# get property(find mode)# will return a dictprint(atm_in_beijing.get_property('address'))
代理模式
您还可以使用handle by agent模式
首先。您需要导入baidumapobject
frombaidumap.objectimportBaiduMapObject
第二。您需要使用一些键和值创建baidumapobject
thu_main=BaiduMapObject(address='北京市清华大学紫荆宿舍')
那么。您需要使用ak_键创建原始句柄
raw_handle=get_handle(ak_key)
最后。您只需调用代理方法来填充baidumapobject的数据
# geography decoder call# it will fill Object with locationthu_main.from_address(handle)# geography encoder call# it will fill Object with address and uid found by location# it will create a list-like BaiduMapObjectthu_main.from_location(handle)# create a object with uidthu_main=BaiduMapObject(uid=thu_main.get_property('uid')[0].uid)# uid info call# it will fill Object with detail info found by uidthu_main.from_uid(handle,detail=True)
对象
jsonlike
__init__(json=dict(), **kwargs)
JsonLike object can be inited with list or dict, you can replace some parameters by decalre kwargs
__str__()
JsonLike object will be transfered as str just like dict
is_list()
JsonLike object can be dict-like or list-like determined by which one init it
get_property(p_key, p_default=None)
if you want to read value of JsonLike, this method is suggested, it will return a dict.
if there is only one result, it will return dict as {key: value}
if there are more results, it will return a list-likedict which contains location
get_properties(p_keys, p_defaults=None)
you can combine two or more properties in one list-likedict
set_property(p_key, p_value)
you can't set key-value using <JsonLike>[key]=value
you are supposed to set property with this method, if there is no p_key in the JsonLike object, you can not set it with this method
keys()
return the keys in the JsonLike object
from_json(json, **kwargs)
reconstruct the JsonLike object by dict or list, can replace some properties by kwargs
to_json()
return dict in JsonLike
位置（jsonlike）
__str__()
location will be formatted as lat,lng
Baidumapobject（jsonlike）
from_uid(handle, detail=False)
fill the BaiduMapObject by uid
needs a handle with valid ak_key
from_address(handle, detail=False)
fill the BaiduMapObject by address
needs a handle with valid ak_key
from_location(handle, detail=False)
fill the BaiduMapObject by location
needs a handle with valid ak_key
